Accomplishments

Short-Term Outcomes
WERA-103 successfully hosted the 2011 Western Nutrient Management Conference in Salt Lake City in March. Approximately 110 professionals from universities, industry and federal agencies attended the conference. Over 35 poster and oral presentations were made on topics related to nutrient management, cropping systems and water and air quality interactions. A large proportion of the presentations were made by graduate students, and awards were made for the top student presentations.

In 2011, committee representatives wrote two nutrient management digest newsletters. These were widely distributed among nutrient management professionals in the western U.S. via an e-mail list serve.

Outputs
Collectively, committee representatives reported publication of 77 refereed journal articles; 52 Extension publications; 38 proceedings and abstracts; 1 book chapter; 3 web sites; and 3 theses for a total of 174 publications focused on various aspects of nutrient management. A complete list of publications is included in the state report attachment.

Activities
The main activity of the group was organization of the Western Nutrient Management Conference in Reno, Nevada. The conference occurred on March 3-4. The conference featured over 35 speakers and over 90 attending, including university, state and federal agency personnel and agriculture industry professionals.

WERA 103 members worked with the International Plant Nutrition Institute to host the WERA 103 web site and archive minutes of meetings, proceedings documents, and other products of the committee. The site is currently under construction but will be located at: https://community.ipni.net/site/wera.nsf/events.xsp

Members of the Committee agreed to write four articles for the American Society of Agronomys Crops and Soils magazine in 2012. This publication targets certified crop advisors and other agriculture professionals with timely information and recertification study/exam opportunities. The CSA News reaches 15,000 professionals across North America.

Committee members Amber Moore and Brad Brown of the University of Idaho developed the Western Nutrient Digest newsletter with contributions from WERA 103 members on nutrient management issues important to western U.S. agricultural systems. Two editions of the newsletter were published in 2011: http://www.extension.uidaho.edu/nutrient/newsletter.html http://www.extension.uidaho.edu/nutrient/pdf/Nutrient%20Digest_Fall2011.pdf

The Committee continues to update the Western States Soil Testing Manual and makes this manual available in electronic or hard copy form at www.spcouncil.com.

Milestones
WERA-103 members generated a master list of nutrient management extension bulletins in the western U.S. These publications address interpretation of soil and tissue tests for the purpose of making nutrient recommendations. The list serves as a reference and resource for committee members and agriculture professionals to seek out information on nutrient management practices. The list also ensures duplication is reduced and gaps in publications can be identified.

Committee members split into three groups to discuss progress since the last meeting toward each of the broad objectives outlined below.

1) Develop and/or improve nutrient recommendations for diverse cropping systems based on soil, water and plant analysis results and management strategies in the Western Region.
a. Procedures for Objective 1:
i. Provide nutrient correlation and calibration data for crops in the region.
ii. Work toward uniformity of nutrient use recommendations for similar crop production systems in the region.
iii. Evaluate and apply new nutrient analytical and interpretive methodologies.
iv. Evaluate the efficacy of new fertilizers and formulations.

Report

Discussion Topic: What is the process of adopting new methodologies? Do emerging method must have some validity/repeatability prior to being placed on evaluation list?

2012-2013 Objectives:
- New model for nutrient recommendations: observational analysis. We need to evaluate how we come up with revised nutrient recommendations with past and limited or no new data, using spatially separated plots.
o Partner with private organizations
- Recommending new methodologies for testing in seven labs (NAPT program). How do we as a regional committee recommend proficiency validation? We are not promoting the method; we just are saying there is sufficient interest that a method be evaluated. - Western Ag Labs nutrient availability probe method is recommended for evaluation by NAPT for proficiency validation with seven laboratories. Joan Davenport will recommend to NAPT.

2) Promote effective use of soil, water, plant, manure, and compost analytical information.
a. Procedures for Objective 1:
i. Integrate analytical test results into nutrient management software
ii. Maintain and update the Western States Soil etc Testing Manual
iii. Review status of soil/plant/water analysis Extension guides and summarize interpretive guidance iv. Explore method for internet distribution of methods manual, analytical interpretation guides etc. Website would be for clientele outreach.

Report

Need to make the Western States Soil Testing Manual more accessible to a wider audience

o Entire manual available on-line: www.spcouncil.com (pdf or hardcopy)
o Key methods (limited) for the West available for free WERA-103 site.
o Joan Davenport to run WERA-103 website, update. Current WERA 103 website is community.ipni.net/site/wera.nsf/home.xsp

2012-2013 Objectives: Promote effective use of soil plant testing information

- Integrate results into nutrient management software  Dan Sullivan regional nutrient management software
- Maintain Western Regional soil Testing manual
-Review status soil water nutrient guides and publications. Develop one searchable database on WERA-103 website for all regional publications.

3) Provide education on the principles of soil-plant-animal-water system management and the tools and practices that lead to sustainable agricultural production.
a. Procedures for Objective 3
i. Facilitate regional education among government agencies, private industry and universities through conferences, websites, extension publications, newsletters, and other appropriate media. ii. Disseminate information within the Western Region to extension educators, private agencies (e.g., Certified Crop Advisors) and other interested parties (e.g., K-12 teachers) through conferences, training the trainer opportunities, and access to published interpretive materials.
iii. Conduct direct education to agricultural producers through conferences, grower meetings, and published interpretive materials.

Report

- Discussion: How do we distribute the newsletter? WERA-103 Logo, Information about the committee and list of editors.
- Location: Univ. of Idaho website, WERA-103.

2012-2013 Objectives:

- Facilitate website transition of WERA-103 website from OSU to WSU  Joan Davenport.
o Update content on website
o Increase visible
- Niche articles inclusion in Newsletter? Can be included in one per Newsletter
- Take proceedings authors to boil them down to have better readability for a wider audience.
- What is our role for K-12 education? There are many organizations who have information on nutrient management. Provide links on website (e.g. Nutrient for life, ag in the classroom). If members have content, send to Joan for inclusion on website.

Impacts

  1. The purpose of a WERA (Western Education/Extension and Research Activities) is to bring researchers together to coordinate related research without the need for a formal multi-state research plan, to organize technical conferences, work groups, task forces, or symposia for exchange of experience and opinions.
  2. The primary impact of the WERA-103 Committee has been to disseminate knowledge through the Western Nutrient Management Conference (biennial basis) for over 20 years. This conference brings agricultural professionals and industry members from the western region together to provide training and communication regarding nutrient management.
  3. The work of the WERA-103 committee has: 1) improved fertilizer use efficiency in the Western Region; 2) improved use of animal waste in environmentally safe ways; and 3)provided information to consultants and governmental agencies that can lead to less nutrient contamination of ground and surface water resources.
